How it works

We estimate your resting energy with the Mifflin–St Jeor equation, then multiply by your activity level.

Formula

BMR = 10W + 6.25H − 5A + s (s = +5 male, −161 female)

Example

A 32-year-old man, 5′10″, 170 lb, lightly active needs about 2,500 calories a day.

Assumptions & limitations

  • Based on population formulas that may not fit athletes, pregnancy, children or medical conditions.
